If the drop in blood pressure is very rapid or excessive, the medulla oblongata stimulates the adrenal medulla , via "preganglionic" sympathetic nerves , to secrete epinephrine (adrenaline) into ...
Downregulation and upregulation. In biochemistry, in the biological context of organisms ' regulation of gene expression and production of gene products, downregulation is the process by which a cell decreases the production and quantities of its cellular components, such as RNA and proteins, in response to an external stimulus.
e. Physiology (/ ˌfɪziˈɒlədʒi /; from Ancient Greek φύσις (phúsis) 'nature, origin' and -λογία (-logía) 'study of') [1] is the scientific study of functions and mechanisms in a living system.

Stress (biology) Schematic overview of the classes of stresses in plants. Neurohormonal response to stress. Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [1] When stressed by stimuli that alter an organism's environment, multiple systems respond across the ...
Depolarization. In biology, depolarization or hypopolarization[1][2] is a change within a cell, during which the cell undergoes a shift in electric charge distribution, resulting in less negative charge inside the cell compared to the outside.

[1] That is, the Bohr effect refers to the shift in the oxygen dissociation curve ...
